Abstract

The detachable solar panel LED desk lamp includes a desk lamp body and a solar cell unit. Through a solar panel on the solar cell unit, the light energy is transmitted to an electricity conversion control circuit board from the solar panel. The electricity conversion control circuit board converts the light energy into electric energy. The electric energy is stored in a battery unit for providing electricity to an LED light source seat of the desk lamp body. The light from the LED light source seat can be circulated and converted by the solar panel of the solar cell unit and then stored in the battery unit again. The present invention can be extensively used and is very convenient for use.
